ABSTRACT
Integrity 2023 is the fourth edition of the successful Workshop on Integrity in Social Networks and Media, held in conjunction with the ACM Conference on Web Search and Data Mining (WSDM) in the past three years. The goal of the workshop is to bring together researchers and practitioners to discuss content and interaction integrity challenges in social networks and social media platforms. The event consists of a combination of invited talks by reputed members of the Integrity community from both academia and industry and peer-reviewed contributed talks and posters solicited via an open call-for-papers. © 2023 Owner/Author.
ABSTRACT
Management of hospital wastewater is a challenging task, particularly during the situations like coronavirus 2019 (COVID-19) pandemic. The hospital effluent streams are likely to contain many known and unknown contaminants including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) along with a variety of pollutants arising from pharmaceuticals, life-style chemicals, drugs, radioactive species, and human excreta from the patients. The effluents are a mixed bag of contaminants with some of them capable of infecting through contact. Hence, it is essential to identify appropriate treatment strategies for hospital waste streams. In this work, various pollutants emerging in the context of COVID-19 are examined. A methodical review is conducted on the occurrence and disinfection methods of SARS-CoV-2 in wastewater. An emphasis is given to the necessity of addressing the challenges of handling hospital effluents dynamically involved during the pandemic scenario to ensure human and environmental safety. A comparative evaluation of disinfection strategies makes it evident that the non-contact methods like ultraviolet irradiation, hydrogen peroxide vapor, and preventive approaches such as the usage of antimicrobial surface coating offer promise in reducing the chance of disease transmission. These methods are also highly efficient in comparison with other strategies. Chemical disinfection strategies such as chlorination may lead to further disinfection byproducts, complicating the treatment processes. An overall analysis of various disinfection methods is presented here, including developing methods such as membrane technologies, highlighting the merits and demerits of each of these processes. Finally, the wastewater surveillance adopted during the COVID-19 outbreak is discussed.

ABSTRACT
The continuous worldwide pandemic of COVID-19 brought about by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a public health emergency of international concern, which was formally announced by the World Health Organization (WHO). The antivirals utilized to restrict the spread of virus and the procedures for the recognition of SARS-COV-2 in wastewater has been reviewed. A main tool Wastewater-based epidemiology (WBE) played a notable role in tracking the spread of corona virus in large community. This review signifies the upgraded clinical impacts and components of Traditional Chinese Medicine (TCM), the function of various antiviral drugs against COVID 19 and the role of human covid to exist in the habitat and the viability countered;with specific spotlight on the advancement of latest strategies to assess the action of latest antiseptic-disinfectants on infections.
ABSTRACT
Worldwide air pollution caused a severe damage to ecosystem by the emission of greenhouse gases. The emission percentage of principal greenhouse gas- carbon dioxide, other gases methane, fluorinated gases and nitrous oxide still not decreased even after the Covid-19 pandemic lockdown. In this regard, many research works were reported on the techniques involved to convert the principal greenhouse gas- carbon dioxide into useful sustainable energy fuel. The advancement in the field of nanoscience and nanotechnology, nanomaterials are used as a photocatalyst to produce energy from greenhouse gas. Carbon nitride is a semiconductor with high stability to produce quantum confinement and reducing the recombination rate of charges, with the introduction of external nanoparticles. It was available in the reports hybrid carbon nitride nanocomposite was employed to reduce the carbon dioxide into valuable products. This review article emerged with an interest towards the carbon nitride’s activeness in the visible region as an effective photocatalyst in the photoreduction of carbon dioxide. Past six years research progress in developing carbon nitride's features to enhance its role in energy production by performing carbon dioxide reduction were given in detail.
